In an interview with Portuguese television channel Sic, Mourinho reviewed his coaching career.
Speaking of the greatest achievement, Mourinho said that he took Porto to the UEFA Champions League in 2004. "We have had many very happy moments, but if I had to choose one, I would choose to take Porto to the Champions League."
"Leading a Portuguese team to the Champions League trophy has a special taste. Since then, no Portuguese team has won the Champions League, and we don't know when we can do it again."
Mourinho also talked about the ghost goal that was eliminated by Liverpool in the 2005 UEFA Champions League. At that time, Chelsea defender Gallas blocked Liverpool forward Garcia's shot on the goal line, but the referee ruled that the goal was valid. Mourinho said: "For Liverpool's goal, VAR will not be effective today, but Real Madrid's exit is more painful and a hit."
